 |
| The model 303 covers 7 major functions for measurement and testing.
DC Voltage: 5 Ranges: 1.2V -1200V Input resistance: 10Megohms Ohms: 5 ranges, 0 Ohms to 1000megohms AC Voltage: 3 Ranges: 0-1200VAC AF Voltages: 3 ranges: 0 -60 Decibels: 5 Ranges: -20 to +63DB Galvanometer: Zero Center for FM discriminator alignment RF Voltage (With accessory high frequency probe) 20Khz-100Mhz |
| The model 200CD Wide Range Oscillator generates frequencies of excellent waveform ( high stability and low distortion) in the subsonic, audio, and ultrasonic ranges. ( 5 Hz to 600 Khz, in five overlapping decade bands ).
Output is 160 MW( 10V) into 600-ohm rated load, 20V open circuit. Power input is 115/230 VAC, 50-1000 Hz, 75 watts. |

| The Hewlett Packard 608 family of RF signal generators are a vacuum tube based mechanically tuned collecton of models. They roughly comprise the 608C, D, E & F and the TS-510 as a militarized HP 608C. Differences are relatively minor between models, mostly involving frequency coverage, however the E&F models have ALC leveled RF output.
Frequency range on all models is 10mhz to 480mhz (or 420mhz for some models), output level is .1uv to 1.0V into a 50ohm resistive load. Attenuator dial calibrated in volts and dbm. Output impedance is 50ohms, internal AM modulation frequencies are 400hz and 1000hz. Almost all variations offer external AM and Pulse modulation capabilities. Output connector is type N female on most models, and type UHF female on the military (TS-510) versions. |
